If you want to discuss Realism Overhaul or how to use Realism Overhaul check out this threadhere.

Due to recent issues arising - please note:

Any issues related to having Kerbal Joint Reinforcement - NEXT installed won't receive support as it produces too many issues related to mods inside of the RO suite of mods. Please use the KerbalJointReinforcement Continued version of KJR. CKAN will install the correct version for you on 1.6.1. Thanks!

Realism Overhaul is a mod that makes Kerbal Space Program behave more like real life. If you're interested in seeing what it's like to fly rockets in the real world, this is the mod for you! Realism Overhaul does this by combining and configuring other mods, and mod and stock parts to perform as their real-life equivalents. You can expect things to be a little harder, and rockets to be a bit bigger, but the scenes far more epic, and the accomplishment that much greater.

Some of the most signfiicant changes include:

Engines have real sizes and performance values, and use real fuels. Most of them have limited ignitions and suffer from ullage.

Pods are as large as their real-life counterparts and weigh what they should.

If you'd like to talk to us, contribute, or ask for help on a bug, you can always find someone online on the RealismOverhaul IRC Channel (irc.esper.net #RO (Webchat, or use a client likeHexChat) or our community discord here: https://discord.gg/WnKNJ8n

If you're experiencing a bug, please post an output_log.txt (This can be found in your /KerbalSpaceProgam/KSP_Data/ folder)

Installation

To install Realism Overhaul you can either use CKAN, or do things manually. IF YOU HAPPEN TO INSTALL IT MANUALLY - USE ONLY THE MODULARFLIGHTINTEGRATOR VERSION SUPPLIED BY KOPERNICUS.

Pre-Packaged installation via CKAN

CKAN is an excellent tool for installing mods in an orderly fashion. We have prepared a set of installation packages for the mods in Realism Overhaul. Here follow instructions for how to install via CKAN (alternatively check out theCKAN User's Guide):

Start out by creating a clean installation of KSP. (If you don't, beware the dragons!)

CKAN offers you two modes of use. You can use the graphical user interface, as explained below, or you can use its command line interface. If you wish to do the latter, check out theCKAN user's guidefor more information on the command line interfrace.

Launch the CKAN GUI by double-clicking the ckan.exe in your KSP directory

Use the Filter to find Realism Overhaul

Select Realism Overhaul to install

Click Go To Changes

Proceed through the menus to select your installation.

Watch CKAN install Realism Overhaul and all the other mods for you

Launch KSP. Enjoy!

Alternative: Manual Installation

If you don't like automation, there's always the old 'by hand' way:

Start with afresh, unadulterated, install of KSP.

Download and install the required mods. Ensure you have the most up to date version and have followed their respective installation instructions.

Download and install Realism Overhaul itself. To do so, download the zip archive and unzip all folders inside its GameData folder into your KSP/GameData folder.

Please see thisGoogle Spreadsheetfor the Current WIP or desired mod packs. Help updating and creating configs is always welcome! Just jump on the IRC channel (details above) and offer your help! If you fix something in one of these packs, please submit it to the Github Repoinstructions here.]

This is a pure "revive" of the last current RO thread which went missing in the forum kraken attack a few weeks back and is still the latest version of Realism Overhaul. Once 1.2.2 RO goes out of prerelease this will be the thread which will be updated as well. Hope that answers your question.

Hum...

Unless for space suits, I don't believe that Texture Replacer add some realism. I believe that it doesn't make the game more difficult too.
Maybe the color isn't chosen very well?

I also think that the links should be updated.

But thanks to you @Theysen for this new thread (where I've a good place too )

This is a pure rebuilt from the waybackmachine of the missing thread. I didn't change anything but will do so over the weekend - since I had exams until now. I will check the links for working versions for the 1.1.3 version of RO. Once 1.2.2 is out those mod links will be updated to the 1.2.2 compatible versions (be it forum threads or forks on github from otherwise deprecated mods). We will also review part mods which got RO compatibility in the mean time to add them in the OP as well. Thanks for pointing out the TR color mismatch

From what @Theysen said, he may have cloned the 1.1.2 thread, and is working on getting all the links for the 1.1.3 versions of the mod, at which point he'll updated this to 1.1.3 (and then 1.2.2 once that's fully ready)

No. Look at the last page and see that this thread has been closed due to creating a new OP back in May of 2016. The new one was originally posted by @stratochief66 - but again: It went missing in the forum voids. As @stratochief66 asked to have a new one created by the waybackmachine this is what I did. I hope this clears your misunderstanding. There is no confusion as you can't even post in the other one.

I have problems engine turning off too early... Does anyone know how to solve this?

If you have TestFlight installed as recommended by RO, then you have your explanation.

TestFlight simulates the lack of reliability of untested rocket engines : more you fly with an engine, more it is reliable.
You can also pay for R&D for engines that increase their reliability for the first time you fly with them.
I encourage you to read the mod's thread to know how it works.

Do you have MechJeb installed and clicked 'Limit Acceleration' ? If you don't leave it a minimum greater than 0, it tries to throttle down - which doesn't work with real engines of course (most of them). Then MechJeb sets throttle to 0 at some point. Try to check those settings.

1) A Venus entry with a lunar rated shield is possible even from an hyperbolic trajectory. I usually set the periapsis above 100km (trajectories mod helps a lot for this) but still a lot depends on your speed and on what your are trying to land.

2) You can do that, you can do a lot of things with Venus atmosphere you can even enter the atmosphere on the dark side and aerobrake until the illuminated side (I think venera 9 and 10 did something similar)

3) Yes, yet you may just need a flat surface to brake you down. Venus atmosphere is very thick.

Been looking around for any news on this - 1.2.2 has been out for a while, when are we getting the update for RO?
Trying to run this on the latest version, and i'll probably just downgrade in a week or so to have RO run correctly.
I'd happily play a dev version of a 1.2.2 RO, if there is one.

Yes! I have the same question. Doesn't it seem a bit like production grinded to a halt?
